|discussion=<p><i>Buckleya distichophylla</i> is an uncommon shrub in the southern Appalachian Blue Ridge Mountains and adjacent Ridge and Valley region; the reason for its rarity is not understood. One hypothesis is that the plants require both direct sunlight and hemlock (<i>Tsuga canadensis</i>) hosts, a rare combination of conditions (A. E. Radford et al. 1968). But other explanations are called for because <i>Buckleya</i> is found in stands lacking hemlock (W. N. Carvell and W. H. Eshbaugh 1982). Moreover, pot-grown plants showed seedling parasitism of 19 different tree species (L. J. Musselman and W. F. J. Mann 1979b); these authors suggested that <i>Buckleya</i> requires a distinctive habitat where hemlock happens to be dominant.</p><!--
--><p><i>Buckleya distichophylla</i> is in the Center for Plant Conservation's National Collection of Endangered Plants. It is not Federally listed, but three states (North Carolina, Tennessee, Virginia) list it as threatened or endangered.</p>
